使用scend-deployer安装下载mef时，执行bash install.sh --install-scene=mef时显示如下内容：

PLAY RECAP ************************************************************************************************************ 

localhost                  : ok=53   changed=14   unreachable=0    failed=1    skipped=60   rescued=0    ignored=0 

run cmd: --install-scene=mef failed, reason: Command '['ansible-playbook', '-i', '/home/ascend-deployer-5.0.0.6/ascend_deployer/inventory_file', '/home/ascend-deployer-5.0.0.6/ascend_deployer/playbooks/process/process_scene.yml', '-e', 'python_tar=Python-3.7.5', '-e', 'python_version=python3.7.5', '-e', 'hosts_name=worker', '-e', 'force_upgrade_npu=false', '-e', 'do_upgrade=true', '--tags', 'mef,copy']' returned non-zero exit status 2.
